Subject: [dpdk-dev] [RFC] testpmd: add ability to set tx IP and UDP parameters
Date: Thu, 5 Apr 2018 14:14:50 -0700 [thread overview]
Message-ID: <20180405211450.31251-1-stephen@networkplumber.org> (raw)
Use RFC standard values address and ports for Tx only test as defaults.
But let the user override those values on command line.
